Should I fetch one or the other? A study on dogs on the object choice in the bimodal contrasting paradigm

The present study assessed how dogs weigh gestural versus verbal information communicated to them by humans in transitive actions. The dogs were trained by their owners to fetch an object under three conditions: a bimodal congruent condition characterized by using gestures and voices simultaneously; a unimodal gestural condition characterized by using only gestures; and a unimodal verbal condition characterized by using only voices. An additional condition, defined as a bimodal incongruent condition, was later added, in which the gesture contrasted with the verbal command, that is, the owner indicated an object while pronouncing the name of the other object visible to dogs. In the incongruent condition, seven out of nine dogs choose to follow the gestural indication and performed above chance, two were at chance, whereas none of the dogs followed the verbal cues above chance. The dogs, as a group, performed above chance the gestural command in 73.6% of cases. The analysis of latencies in the above-mentioned four conditions exhibited significant differences. The unimodal verbal and the gestural conditions recorded a slower performance than both the bimodal incongruent and congruent conditions. No statistical differences were observed between the unimodal and bimodal conditions. Our results demonstrate that dogs, trained to respond equally well to gestural and verbal commands, choose to follow the indication provided by the gestural command than the verbal one to a significant extent in transitive actions. Furthermore, the responses to bimodal conditions were found to be quicker than the unimodal ones.     

EEG decoding of semantic category reveals distributed representations for single concepts

Achieving a clearer picture of categorial distinctions in the brain is essential for our understanding of the conceptual lexicon, but much more fine-grained investigations are required in order for this evidence to contribute to lexical research. Here we present a collection of advanced data-mining techniques that allows the category of individual concepts to be decoded from single trials of EEG data. Neural activity was recorded while participants silently named images of mammals and tools, and category could be detected in single trials with an accuracy well above chance, both when considering data from single participants, and when group-training across participants. By aggregating across all trials, single concepts could be correctly assigned to their category with an accuracy of 98%. The pattern of classifications made by the algorithm confirmed that the neural patterns identified are due to conceptual category, and not any of a series of processing-related confounds. The time intervals, frequency bands and scalp locations that proved most informative for prediction permit physiological interpretation: the widespread activation shortly after appearance of the stimulus (from 100 ms) is consistent both with accounts of multi-pass processing, and distributed representations of categories. These methods provide an alternative to fMRI for fine-grained, large-scale investigations of the conceptual lexicon.     

Extinction partially reverts structural changes associated with remote fear memory

Structural synaptic changes occur in medial prefrontal cortex circuits during remote memory formation. Whether extinction reverts or further reshapes these circuits is, however, unknown. Here we show that the number and the size of spines were enhanced in anterior cingulate (aCC) and infralimbic (ILC) cortices 36 d following contextual fear conditioning. Upon extinction, aCC spine density returned to baseline, but the enhanced proportion of large spines did not. Differently, ILC spine density remained elevated, but the size of spines decreased dramatically. Thus, extinction partially erases the remote memory network, suggesting that the preserved network properties might sustain reactivation of extinguished conditioned fear.     

How New Knowledge About Parenting Reveals the Neurobiological Implications of Intersubjectivity: A Conceptual Synthesis of Recent Research

Observations of early mother–infant interactions have shown that intersubjectivity is a primary motivation and have underscored the importance of maternal competencies in this development. In our paper we propose a conceptual overview of the different perspectives according to which parental caregiving has been formulated. Psychoanalytical theory has fundamentally promoted the exploration of maternal and paternal intrapsychic constellation, by stressing the role of unconscious processes in parental attitude as well as in infant development. In contrast with psychoanalytical theory, the conceptual framework of attachment has mostly considered real interactions between parents and infant, underlining parental abilities in providing the infant with a secure base. Finally, infant research has explored the complexity of communicative system between parents and infants, which appears already active from the birth of the baby. Recently, these different viewpoints have been broadened by neurobiological research, which has begun to explore maternal brain functioning and structure, by means of new scientific instruments such as fMRI techniques. From these perspectives, we provide an overview of motherhood, underlining both neurobiological and psychological transformations, which begin from pregnancy and run through the first year of the infant, when the mother–infant intersubjective matrix is built. This matrix influences the construction of the infant's Self and support the development of the sense of “we,” a sort of connective net, which ties the baby to parents, letting him feel as a part of the familiar world.     

Ordeal by Fire: The Tragedy of the Solar Temple

On October 4th and 5th, 1994, fifty-three people were found dead in Switzerland and in Canada. Their bodies—some showing signs of violence suffered before the fires—were found in the incinerated centres of a neo-Templar movement called originally International Order of Chivalry Solar Tradition or, for short, Solar Tradition, and after 1990-91 Order of the Solar Temple. The movement is part of one of several currents which as a whole compose the universe of the contemporary occult-esoteric movements, the neo-Templar tradition. In this paper I propose to trace, first of all, the history of the neo-Templar tradition, then that of the Solar Temple, relating the essential information on the tragedy of October 1994, and finally suggesting some possible interpretations.     

The Relationship Between Levels of Guilt in Thematic Stories and Unsocialized Behavior

Many previous studies on the relationship between inhibition of expression of hostility in thematic stories have focused on the severity of the punishment rather than the quality of the guilt expressed. Using a more subtle approach, it was found that an increase in the level and quality of guilt expressed in TAT stories was significantly associated with a reduction in unsocialized behavior. The results suggest that an analysis of guilt along dimensions of internalization, the concern for others, and the desire to change offers a way of dealing with thematic productions that is more consistent with our clinical observations and understanding.     

How the mind understands other minds: cognitive psychology, attachment and reflective function

Jung's epistemological relativistic attitude was very advanced for his time and very much in line with the contemporary philosophy of science. Further, Jung states that the patient's unconscious has the capacity to represent itself by creating metaphors which give the therapist all the help he might need in treating his patient. As such, Jungian analysts have not been encouraged to embark on theoretical work and as a result, the Jungian movement has been lacking those theories that connect general psychological principles with clinical practices. In an attempt to enlarge our 'middle-range theories', we shall discuss Peter Fonagy's concept of reflective function. In our opinion, the theoretical hypothesis regarding the instinct of reading the mind (Baron-Cohen 1995) and Fonagy's idea of reflective function are extremely useful in our Jungian clinical practice and these concepts are utilizable because they are not at odds with analytical psychology's general epistemological and theoretical framework.
